  • Patent number: 8800724
    Abstract: A modular, self-supporting elevator hoistway system and method includes stackable cages to replace structural building hoistways. Vertical corner columns, extending upward from an adjustable footing anchored in the elevator pit, form planar sides surrounding the hoistway. Fireproof sheeting between the columns isolates the hoistway interior from the rest of the building. Adjustable sill supports extending from adjustable horizontal cross members allow precise alignment with building floor doorways. Vertical elevator guide rails coupled to cross members cooperate with guide shoes on elevator cars to deter horizontal oscillations and smooth vertical motion of the car. A hoist beam atop the uppermost cage may support of an elevator car during maintenance. Cages may be assembled separately and installed in modular segments as the height of the building progresses, and may be erected before construction of building floors, allowing floors to be built to match hoistway sills.

  • Publication number: 20120325592
    Abstract: An elevator includes a compensating device having the purpose of providing compensation for changing weight of a support on the cage side or on the counterweight side. Depending on the respective position of an elevator cage and a counterweight in the elevator shaft there are more meters of the support on the cage side or on the counterweight side. In the case of a small support length on the cage side, a large compensating device length on the cage side results and conversely. The compensating device suspended at the elevator cage and at the counterweight forms a loop in a shaft pit and can be set in oscillation. Provided as a remedy are, for example, rods which guide and stabilize the compensating device.

  • Publication number: 20120152663
    Abstract: In this elevator system, a traveling body has arranged upon it a safety gear for braking and holding the traveling body tight on the guiderail, or on a braking rail. The safety gear is connected to a device for actuating the safety gear, which can also actuate the safety gear. The device for actuating the safety gear contains a coupler body, which can be pressed against the elevator hoistway, possibly against the guiderail or braking rail, wherein actuation of the safety gear is effected by a relative movement between the pressed-on coupler body and the safety gear. For this purpose, the coupler body can contain a curved coupler surface, which, in case of need, is brought into engagement with the elevator hoistway, or with the guiderail or braking rail.

  • Publication number: 20120061190
    Abstract: An elevator installation includes an elevator cage with a support construction carrying the elevator cage, wherein the support construction has two beams. Mounted on each beam is a positioning arrangement on which, for example, a sensor is positioned, which is part of a load measuring device, wherein the positioning arrangements have material structures or sensor carriers. The sensors detect a change in spacing of the material structures or of the sensor carriers from one another, wherein this change in spacing is caused by a change in loading of the elevator cage. Signals of the sensors are processed in an evaluating unit and a signal representing the loading is used in an elevator control.
